Before electricity, doorbells rang via a complex rigging of mechanical pulleys. Visitors pulled a rope or turned a key-like affair — think Downton Abbey’s elaborate system to summon staff, but on a smaller scale for the masses.

The electric doorbell was invented in 1831, and by the early 1900s was all the rage. Chimes and bells could be heard from anywhere in the house; a tremendous convenience for homeowners and visitors alike.

Today, you can coordinate the look and sound of your doorbell to your home’s style. You also can embrace the internet age with video doorbells that can be answered from thousands of miles away.

If you’re renovating an older home, the retailer Rejuvenation has several retro-style doorbells.

There’s a round oak bell, popular in the late 1800s and early 1900s, with a porcelain button. A midcentury starburst style comes in chrome or brass. And a couple of vintage-look ones are stamped with a “ring” or “please ring” note, in oil-rubbed bronze or burnished finishes. (www.rejuvenation.com)

Ready to go high tech with your entryway?

Having a “smart” doorbell, with video, allows you to keep an eye on your front door area, not only for visitors but for packages. With many of these units, you can speak with the person ringing your bell, chatting directly with the FedEx or UPS driver, for instance, about where and when to leave a delivery.

According to Consumer Reports’ Eric Hager, the smart doorbell business has grown enormously in the last several years. He acknowledged concerns about tech systems’ vulnerability to hackers, but said homeowners seem willing to take on those risks for the convenience and other safety features of smart doorbells.
